可以看到直接在xib中属性设置的圆角边框成功啦！

贴一下代码.h

IB_DESIGNABLE  // 动态刷新
@interface UIView (YHXibExtension)
@property (assign, nonatomic) IBInspectable CGFloat cornerRadius;
@property (assign, nonatomic) IBInspectable CGFloat borderWidth;
@property (strong, nonatomic) IBInspectable UIColor *borderColor;

@end

贴一下代码.m

@implementation UIView (YHXibExtension)

@dynamic cornerRadius;
@dynamic borderWidth;
@dynamic borderColor;

- (void)setCornerRadius:(CGFloat)cornerRadius {
    self.layer.cornerRadius = cornerRadius;
    self.layer.masksToBounds = (cornerRadius>0);
}

- (CGFloat)cornerRadius {
    return self.layer.cornerRadius;
}

- (void)setBorderWidth:(CGFloat)borderWidth {
    self.layer.borderWidth = borderWidth;
}

- (CGFloat)borderWidth {
    return self.layer.borderWidth;
}

- (void)setBorderColor:(UIColor *)borderColor {
    self.layer.borderColor = borderColor.CGColor;
}

- (UIColor *)borderColor {
    return [UIColor colorWithCGColor:self.layer.borderColor];
}
